Which hard drive type would be best to use by the army when writing operational data while traveling in a jeep in rough terrain?

They should use an SSD.

Explanation:

The fact that the writing operation takes place in a jeep in rough terrain suggests that they should be using an SSD (Solid State Drive) which unlike HDD's, don't have a spinning disk and a head that writes data on it. So there are no moving parts in an SSD,  and they have about 30 times more resistance to shock/vibration damage which is really helpful in this situation.

I hope this answer helps.
